- edge curledback on itself at 18 and embedded This invention relates to fibre cans or containers provided with frangible seals at the top and having metallic closures for protecting the frangible seals until received by the consumer.

The invention concerns itself more particularly with improvement in construction of the parts entering into a screw connection between the body and the cover and holding the frangible seal in place.

1o'-- An important object of the invention is the provision of a cam, closed as above described, and in which the parts will be constructed in such manner that a metallic collar holding the frangible seal firmly in place and providing threads for-interlocking engagement with a flanged separate cover will greatly strengthen the open end of the fibre body and protect the cover flange from being forced out to disrupt the threaded engagement, and will securely hold the frangible seal in sealing position and protect it until received by the consumer.

Another important object of the invention is a can or container of the character described, in which the raw edges of the band or collar will be turned into or toward the material in rounded form to the end that no raw or sharp edges are presented to cut the hand of the consumer, or to cut the material of the container body and the frangible seal. 30 Numerous other objects and advantages of the invention will be apparent as it is better under stood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure l is a perspective view of one form of container "embodying the present invention and illustrating the metallic cover lifted and separated from the container; and

Fig. 2 is a fragmentary longitudinal sectional View, on an enlarged scale, of the sealed container with its metallic cover in closed position.

For the purpose ofillustrating a preferred embodiment of the invention there is disclosed in the drawing a container formed with a fibre body II on the bottom end of which is secured a metallic bottom or end l2 having its marginal edge I3 (Fig. 2) bent into sealing position with the end of the body.

being bent inwardly in an annular horizontal wall It which merges into a vertical flange I1 55 on the inside of the body wall and has its terminal the container.

into the fibre wall ll.

A frangible disc 2| is used to initially close the end of the container, and this disc has its peripheral edge 22 clamped in between the curled 5 edge l8 of the collar flange l1 and the body wall ll. As illustrated in Fig. 2, this peripheral edge of the disc is embedded in the body wall with the-inside terminal edge of the collar flange l8. Breaking of the frangible seal effects opening of A metal cover is provided and is adapted to seat upon the wall l6 of the collar IS in which position (Fig. 2) it encloses and protects the frangible seal 2|. The cover 25'is bent downwardly into an encircling flange 26 which passes over the outside of the collar l5 when the cover is applied to the container.

Provision is made for locking the cover 25 I on the container and for this purpose the cover 20 also disposed at. an angle to the rim of the collar so that by applying the cover 15 onto the end of the container and rotating it in a clockwise direction (Fig. 1) the threads 21 engage beneath and interlock with the threads 28 of the collar. This rotation of the cover draws it tightly down against the wall I6 of the collar and looks it in closing position on the container.

Downwardly extending locking lugs 29 may be struck out from the collar wall at oneend of the threads 28 l and in applying the cover 25 its threads 21 are sprung out over the lugs 29 and aremoved past the lugs. with the cover in closed position, the'selugs 29 form locking means to resist the backward turning of the cover and to preventaccidental displacement or loosening of the cover, the lugs being in the path of the threads 21 when the cover is turned in a reverse or backward direction. In removing the cover, therefore, it is necessary to again spring its threads 21 out and over the locking lugs 29.

The bottom edge of the collar I5 is curled inwardly and upwardly against the body wall into a curled bead 3| which is spaced from the lower edge of the cover flange 26 when the cover is'in closed position. This bead protects the lower edge of the cover, its outer diameter being 'substantially the same as the diameter of the cover wall.

By reason of the inturning or curling of the flange edge it on the inside of the container and the curling of the lower edge of the collar toproduce the head 3! all of'the raw edges of the collar are turned inwardly out of exposed position. The curled edge on the inside of the container prevents the contents coming into contact with any raw edge and the outer curl prevents exposure of the raw edge on the outside of the can. The flange it is or may be turned up into partial parallelism with .the inner surface of the body so as to indent the same without cutting the material of the frangible disc.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form,

construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material, ad-

vantages, the form hereinbefore described being 'merely a preferred embodimentthereof.
